Re: Low pressure or high pressure Dil / O2 cylinders

I get confused with American sizing - so how do new cylinders compare in gas volume stored to 3l 232 bar steels - which I use.

There are approximately 28l(28.3 to be more specific, but we'll use 28 for simplicity) of gas per cubic foot. Therefore, a 3l cylinder at 232 bar(3410psi) will have 696l of gas, or 24.8 cuft. At 2640psi(180 bar), which is what LP steel cylinders are rated for in the US, it contains 540l of gas, or 19.3 cuft.

The Worthington cylinders, based on Deep Thought's posted numbers, are approximately 1.55l(for the 13cuft cylinder) and 2.27l(for the 19cuft cylinder), but are rated for 3442psi(234 bar).

Clear as mud?
